Oh, those "tomatoes" are Rosehips. :-)
Great for tea and what ails ya. :-D

Though I do agree that they are Rugosa roses, I don't think of them as wild. There may be some that are wild, but non are native to the US and there are some great hybrids.

Here is a link that might be useful: Hybrid Rugosa roses

By your description of a thorny plant with tomato-like fruit, I was all ready to say it was horse nettle, till I saw the photos and the mention of rose hips. I never thought of it, but they kind of do resemble tomatoes.

pitimpinai: yes, the fourth picture is the trunk of the same plant.

Thank you very much! My parents have planted many a rose in that garden so I'm not surprised it's some type of rose plant. That's very cool that those are rose hips; awesome to have on hand if needed. I really appreciate the help!
